What are the best backup methods and tools for LANs?

由人工智能和领英社区提供技术支持

A local area network (LAN) connects multiple devices, such as computers, printers, and servers, within a limited geographic area. A LAN can improve communication, collaboration, and productivity among users, but it also requires regular backup and recovery to protect data and prevent downtime. In this article, you will learn about the best backup methods and tools for LANs, and how to choose the right ones for your needs and budget.

1 Backup methods

When deciding which backup method to use for your LAN, you should consider how much data you have, how often you need to back it up, and how fast you need to restore it. A full backup provides the most complete and reliable backup, but it also takes the longest time and the most storage space. Alternatively, an incremental backup saves time and storage space, but it requires more steps and resources to restore the data. Finally, a differential backup is faster and simpler to restore than an incremental backup, but it uses more storage space as it duplicates some data.

Some backup software tools support a method called reverse incremental. In this method the latest backup is always a full backup and older data (at disk block level) is ejected out into incremental restore points. This works particularly well for cloud backups or where there is a need to roll a full backup down onto tape every day.

2 Backup tools

When it comes to backing up data on your local area network (LAN), there are various tools you can use depending on the backup method, storage device, and features you need. For instance, Windows Backup is a built-in tool included with Windows operating systems. It enables you to conduct full, incremental, or differential backups of LAN data to an external hard drive, a NAS device, or a DVD. Additionally, this tool creates a system image which is a copy of the entire system including settings, applications, and files. Macrium Reflect is another third-party option for Windows operating systems that allows for full, incremental, or differential backups to an external hard drive, NAS device, or cloud service. It also creates a system image and provides encryption, compression, and scheduling features. Acronis True Image is an additional third-party tool that works with both Windows and Mac operating systems. It also enables you to perform full, incremental, or differential backups of LAN data to an external hard drive, NAS device or cloud service. Moreover, this tool creates a system image and offers features such as encryption, compression, scheduling, ransomware protection, and file sync.

3 Backup frequency

The frequency of your backup should depend on the rate of data change in your LAN and the amount of data loss you can handle. It is best to back up your LAN data as frequently as possible, but this may not be feasible or economical for some situations. A practical approach is to follow the 3-2-1 backup strategy which involves having at least three copies of your data (one on your LAN, one on an external storage device, and one on a cloud service or a remote location), using two different storage media (such as hard drives, NAS devices, DVDs, or tapes) and keeping one copy offsite (on a cloud service or a remote location) to protect against disasters, theft, or sabotage.

4 Backup verification

Verifying your backup is essential to ensure that you can restore your data in case of failure or disaster. There are various ways to do this, such as using checksums to detect any errors or corruption that may have occurred during the backup process, performing test restores to verify the data is readable and functional, and reviewing reports and logs generated by backup tools to monitor and troubleshoot performance and issues.

5 Backup best practices

To ensure your backup methods and tools for your LAN are effective, you should plan your backup strategy and identify the critical data and systems that need to be protected. Additionally, it is important to encrypt your backup data and label your backup media for easy organization. Finally, testing your backup and recovery processes is necessary to guarantee they are functioning correctly and meeting the requirements.

In a Windows server environment there's a lot to be said for Volume Shadow Copy. While perhaps not a backup method in the fullest sense it is a great way to have regular block-level snapshots taken on a regular basis outside the available backup window which can support almost instantaneous restores that can even be performed by end users, given five minutes of training.
